MG Im5 vs Ferrari Roma

What's the difference?

The MG IM5 Performance is fast, comfortable, quiet and super refined. Putting some minor spec and active safety niggles to one side, it offers the features, tech and price to match it with its well-credentialled and already popular mid-size EV sedan competitors. Is there room for one more? We think there should be.

The Ferrari Roma is like a trained assassin in a Zegna suit - capable and clinical yet stylish and effortlessly superior. We believe there’s a replacement coming later this year and it will have to be doing well to top this superb machine.

Playing spot the straight line on the outside of the MG IM5 is like an automotive design version of Where’s Wally? There aren’t many, in the midst of an unrelentingly curvaceous exterior treatment.

At close to five metres long and two metres wide the IM5 is appreciably longer (+211mm), a little wider (+27mm) and a bit taller (+33mm) than a Tesla Model 3. Think BMW 5 Series in terms of overall size.

And the soft-form shape is functional; the swoopy liftback boasting an ultra-slick 0.24 drag coefficient.

That said, I’m not convinced by the ‘Periscopic’ cameras informing the driver assistance systems from the front guards. They scream tacked-on afterthought. But a touch-only initial opening function for the flush door handles is cool and makes life easier.

The curves continue inside with soft-padded surfaces around the dash and doors, but the straight edge obviously came out for the 10.5-inch central media screen and vast 26.3-inch upper display. There are next to no buttons; even exterior mirror adjustment is directed from the screen to a multi-function steering wheel control.

System software (powered by a Qualcomm ‘Snapdragon’ chip) is lightning fast with a two-finger up and down swipe shortcut function on the central screen for ventilation and other functions.

The interior is light and bright thanks to the enormous panoramic sunroof. It’s been fine in cooler winter conditions during this test but it could be interesting to revisit in the heat of an Aussie summer

There are two interior colour schemes available - the ‘Highland Grey’ of our test car or ‘Dover Beige’ for those brave enough to live life with the threat of scuff marks on your shiny new car’s glamorous but vulnerably light interior.

If you’re looking for a flash Fazza with spoilers and vents at all points of the body, you’ve come to the wrong coupe.

The Roma is a subtle, beautifully balanced and delicately detailed two-door inspired by all-time Ferrari classics like the 250 GT Lusso and 275 GTB.

Its proportions are impeccable with complex curves and sweeping lines combining to produce an exquisitely pure shape.

Slimline LED headlights are divided by horizontal DRL strips, the broad bonnet incorporates a quietly muscular power bulge and the minimalist ’egg crate’ grille sits below a sharply chiseled nose.  

I’m a particular fan of the split wedge-shaped tail-lights, seamlessly incorporated into the upper deck of the rounded rear end. The active rear spoiler is also neatly hidden away in the leading edge of the boot lid. No shoutiness here, even the exterior badges are works of art.

Crack open the bonnet and the engine sparkles like a jewel in a display case. Scarlet red crackle finish on the intake plenums and cam covers make it pop like a firecracker. 

The interior follows a dual cockpit theme with twin curved sections divided by a flying buttress style console between them housing the gear selection gate and central media screen.

Flashes of carbon-fibre and chromed alloy add a touch of overt raciness, Alcantara on the dash and doors echoes the ‘mouse fur’ of Ferraris past and the contrast stitching around the cabin is flawless. 

The sleek front seats feel as good as they look, the typography of the Roma badge on the passenger side of the dash is super cool, and overall the interior is snug and ultra classy. 

There’s plenty of breathing room up front and in terms of storage one of the first things worth calling out are the long but relatively narrow door bins. No good for anything above unusually slender bottles, even if they’re lying down.

No conventional glove box in the dash, but there is a large lidded box (cooled and heated) between the seats that doubles as a centre armrest. It’s supplemented by a big stowage area underneath the flying buttress style centre console.  

There are two cupholders in the centre console as well as a wireless device charging pad in front of them with a vaguely phone-shaped oddments bin alongside it.  

Move to the rear and the IM5’s 75mm wheelbase advantage over the Tesla Model 3 is clear. Heaps of knee and headroom for me at 183cm sitting behind the driver’s seat set to my position. 

But… the seat sits low which pushes your knees up into the air to the point where my thighs are not contacting the seat cushion. Even though the rear seat reclines to a certain degree it’s a problem compounded by a chronic lack of room for your toes under the front seat. Awkward.

There are map pockets in the front seatbacks, modest bins in the doors and a fold-down centre armrest with two cupholders. Adjustable ventilation in the rear of the front centre console always makes life in the rear seat more pleasant.

The car also houses ‘Strong Magnets’ at various points around the cabin and boot, with a configurable adapter able to lock a phone or tablet into place for the entertainment of, in our case, back seaters. 

Speaking of devices for entertainment, there are two USB-C sockets and a 12-volt outlet in the front and another USB-C and 12V in the back, so charging isn’t an issue. 

The IM5 is a liftback so the boot aperture is generous and a capacity of 457 litres with the rear seats up is decent for a car of this size, although that’s less than the Tesla Model 3 (594L) which has an additional well under the floor. 

Still, enough room for the largest (124L) and smallest (36L) suitcases from the CarsGuide three-piece luggage set with some room to spare.

The power tailgate can be operated hands-free via the key or an always welcome under bumper kick function.

Volume expands to 1290 litres with the rear seats folded and there’s a modest 18-litre ‘frunk’ under the bonnet.

The bad news is a repair-inflator kit rather than a physical spare wheel, but the better news is the IM5 Performance can tow a 1500kg braked trailer (750kg unbraked).

The IM range also features the ‘MG iSmart’ app allowing remote control of various functions including charging, checking vehicle location and route planning. 

At close to 4.7m long, the Roma isn’t compact but its supercar stance comes courtesy of a close to 2.0m width and low-riding 1.3m height (with a 2670mm wheelbase).

The cabin is cozy, as intended, but at 183cm I still have ample headroom in the front. The rear is a different story with the two ‘+2’ seats serving as occasional emergency spots only or a handy option for smaller kids.

For storage there are slim but long pockets in the doors, a surprisingly generous glove box, a wireless charging pad under the centre console, phone-size slits on either side of that console, a single cupholder between the front seats with a lidded box (containing 12V and USB-A outlets) behind it.

There’s a recess for oddments on the transmission tunnel between the rear seats, and armrests either side in the back.

The boot holds 272 litres, which is enough for several soft bags, rising to 345 litres with the 50/50 split-folding rear seatbacks lowered. There are tie-down anchors, which is handy but be aware there’s no spare, only a repair/inflator kit.

Overall, not exactly SUV-like in terms of day-to-day practicality but at least on par with its key competitors.

At $453,000 before on-road costs, the Roma Coupe lines up almost directly with a trio of well-credentialled, well-equipped and ultra-fast 2+2 supercars - the Aston Martin DB12 ($455,000), Maserati GranTurismo Trofeo ($450,000) and Porsche 911 GT3 ($446,700). 

If you prefer a roofless experience, the Roma Spider convertible will set you back $520,300 (BOC).

And as you’d expect, the standard features list is impressive; the options list even more so.

Aside from the safety and performance tech covered a little later, highlights include 18-way power front seats, full-grain Frau leather trim, eight-speaker JBL audio (with digital radio), dual zone climate control, an 8.4-inch hi-definition central media display, a 16-inch (highly) configurable instrument cluster, adaptive cruise control and 20-inch forged alloy rims.

There’s also LED exterior lighting (including auto dusk-sensing headlights), Android Auto/Apple CarPlay connectivity, rain-sensing wipers and built-in nav, as well as Alcantara, chromed aluminium and carbon-fibre trim details. There’s more, but you get the idea.

And when it comes to options, the sky’s the limit with the likes of carbon-fibre everything, beefier audio as well as custom colour and trim options available through Ferrari’s ‘Tailor Made’ and ‘Special Equipment’ programs.

One popular addition is an 8.8-inch HD touchscreen for the front passenger (co-pilot?) displaying data on the car’s performance and status as well as allowing selection of music, sat-nav info and climate functions. Super cool and it will set you back $9500.

The MG IM5 Performance is powered by an electric motor on each axle - the rear (372kW/500Nm) more powerful than the front (200kW/300Nm), for overall outputs of 572kW (that’s close to 770hp) and 802Nm of pulling power.

The official term for that amount of grunt is… a lot. And we’ll get to what it means on the road in the Driving section shortly.

Enzo Ferrari famously said “aerodynamics are for people who can’t build engines” and notwithstanding the fact the Roma is slippery in the wind tunnel (Cd .30), its front-mid mounted 3.9-litre turbo-petrol V8 engine would surely meet with il Commendatore’s approval.

Sending drive to the rear wheels via an eight-speed dual-clutch auto transmission, this all-alloy, 90-degree unit features dual twin-scroll turbos, a flat plane crank, dry sump lubrication, direct fuel-injection and a single-piece cast exhaust manifold to produce 456kW from 5750rpm to the 7500rpm rev ceiling, and 760Nm from 3000-5750rpm.

Worth noting its 'front-mid' placement as the entire block is positioned low down and behind the front axle centre line.

The MG IM5 Performance features an 800-volt electrical architecture which means the 100kWh NCM battery can accept a DC peak charge of close to 400kW.

Only snag is the highest you’ll currently find in Australia is 350kW. But even at that rate you’ll still be looking at a 30-80 per cent charge in just over 15 minutes. Maximum AC charge rate is 11kW.

Claimed range is 575km (WLTP) which is less than the Tesla Model 3 Dual Motor AWD at 629km.

Over a week of city, suburban and some freeway running we saw average energy use of 20.6kWh/100km which is on the high side for an EV of this size but maybe not for one with this kind of performance potential. 

The Roma’s official (WLTP) fuel consumption figure on the combined (urban/extra-urban) cycle is 11.2L/100km, the 3.9-litre turbo-petrol V8 emitting 255g/km of CO2 in the process.

Not exactly miserly, but even with that engine begging to be revved we saw an average of 12.9L/100 over a combination of urban shuffling, twisting B-roads and some freeway running.

A start/stop function is standard and with an 80-litre fuel tank on board, the Roma’s theoretical range is around 715km, dropping to approximately 620km using our real-world number.

First things first, the IM5 Performance is supercar fast. This 2.3-tonne five-seater blazes from 0-100km/h 3.2 seconds and with its dual motors combining to produce 572kW/802Nm, eye-widening performance always resides underneath your right foot.

But it’s not all about straight line speed. Ride comfort is excellent. Underpinned by an all-new platform, the IM5’s suspension is by double wishbones at the front and multi-links at the rear. But the key to its bump and rut smoothing ability is air suspension and ‘continuous control’ active damping.

Fold in double-glazing on the full-length glass roof and side windows, as well as active noise cancellation and you have a serene interior environment at any speed. Also worth noting the front seats are great; as grippy as they are comfortable.

Not only that, despite its relative heft, this mid-sizer steers well, too. Not the last word in road feel but it points accurately and the standard rear steering helps with prompt (but never jerky) cornering turn-in. Flick to ‘Sport’ mode and the IM5 is up for some enthusiastic running.

The rear wheels can turn up to 12 degrees in the opposite direction to the fronts at slow speed, which makes for a usefully tight 10-metre turning circle. But above that, at lesser angles, it adds extra stability and decisiveness in the way the car steers through even tight, twisty sections.

Rubber is top-shelf Pirelli P Zeros on 20-inch alloys (245/40 fr - 275/35 rr) and it grips hard, especially in the wet weather over much of the test period. Braking is solid, as it needs to be, with ventilated discs all around and four-piston callipers at the front. 

No adjustable regen braking but you can feel the ‘Cooperative Regenerative Brake System’ (CRBS) doing its thing when you lift off the accelerator. 

The physical rear view is modest thanks to the slope of the back window reducing its functional area for the driver to that of a 1950s VW Beetle. Even the interior rear-view mirror is tiny and folds up into a recess in the headliner if you’d prefer life without it.

But that’s where a rear camera view popping up on the upper screen display (accessed via the right-hand steering wheel click control) comes in handy. Side camera views are also available as is a 360-degree overhead view, which makes parking straightforward.

If you need more parking help there are various self-parking modes including a nifty ‘Curbside’ function that will realign the car hands-free if you’re parallel parked too far out from the kerb.

In a similar vein, a ‘Rainy Night’ mode projects left and right rear views onto the main screen using AI to enhance clarity and highlight pedestrians and cars.

Overall the ADAS (Advanced Driver Assistance Systems) are relatively unobtrusive but we found ourselves switching off the incessant overspeed chime that sounds for 10 seconds if you creep over the indicated speed limit, even when the system has misfired on the correct speed. For example, 40km/h school zones on a Sunday.

The over-zealous driver distraction warning also occasionally issued a visual and audible slap on the wrist when I was looking straight ahead. Tellingly, there’s a specific quick screen for turning both these functions off, but it kinda defeats the purpose of having them in the first place.

We also found the adaptive cruise control to be hesitant in multi-lane environments, reducing speed occasionally because the system seemingly believed a car was set to merge, when it wasn’t.

Press the PS (Partenza Sportiva) button on the console, slip the manettino control on the steering wheel into ‘Race’ mode, left-foot brake (hard) and floor the throttle. Wait for the PS light on the dash, keep the accelerator pinned and lift off the brake.

Ferrari says the Roma will then proceed to accelerate from zero to 100km/h in 3.4 seconds, and in the interests of a thorough assessment I may have found a quiet light commercial area near Maranello, replicated this procedure and validated the claim.

Yes, even at 1570kg, with 760Nm of pulling power available from 3000-5750rpm, the Roma is exceptionally fast in a straight line. And the twin-turbo V8 that’s been so reserved and docile around town lights up to deliver glorious engine noise and a characteristic exhaust howl.

A flat-plane crank arrangement often makes a vee engine lumpier than a more conventional cross-plane design, but it will rev hard and fast, and in this case the compact size of the Roma’s twin turbos enhances throttle response even further.

Speaking of the turbos, variable boost management helps to smooth acceleration while keeping an eye on fuel economy and despite the flat-plane configuration this engine is perfectly civilised.

A tall top (eighth) gear makes for easy cruising but the tight B-roads and lesser highways we spent most time on didn’t allow for any high autostrada speeds.

But how’s this for a flex? Ferrari says the active rear spoiler will stay in its low-drag position until the car hits 100km/h, then pushing through medium and high drag (135-degree) positions as speed rises. But… “over 300 km/h, the spoiler is always in MD mode because in such conditions it is preferable to have a more balanced car”.

Suspension is by double wishbones at the front with a multi-link set-up at the rear and twin solenoid (magnetic) adaptive dampers all around.

Rubber wrapping the 20-inch forged alloys is top-end Michelin Pilot Sport 4 S (245/35 fr / 285/35 rr) and front-to-rear weight distribution is 50/50.

What that all adds up to is a comfortable, responsive and deeply satisfying drive experience. In standard Ferrari fashion the dual-clutch transmission is rapid-fire perfection, the steering is light but accurate and feelsome, while the in-cabin ergonomics are superb.

Push as hard as you dare in tight, flowing corners and the car just continues to grip and bait you to try harder. And if you do give in and start to run out of talent the ‘Active Yaw Control’ and limited-slip ’E-diff’ will step in to imperceptibly save your bacon.

Moving the manettino through its five positions - ‘Wet’, ‘Comfort’, ‘Sport’, ‘Race’ & ‘ESC-Off’ rapidly transforms levels of ride comfort, steering, transmission and engine response. You can also set the ride to Comfort with other attributes dialled up to 11 for a cross-country sweet spot. 

And when it comes to slowing rather than going, the Brembo brake set-up is circuit ready with vented carbon ceramic rotors all around (390mm fr / 360mm rr) clamped by six-piston calipers at the front and four-piston units at the rear. They take a while to warm up, but never feel anything other than mega. 

No surprise, ANCAP and Euro NCAP have not assessed the Roma, but you could mount a solid case that the car’s high-level dynamic ability is its greatest active (crash avoidance) safety system. 

Over and above that there are the usual anti-lock brake, traction and stability control systems (the latter is Ferrari’s adjustable SSC ‘Side Slip Control’) as well as AEB (with vehicle and cyclist detection), adaptive cruise control, lane-keeping assist, lane departure warning, blind-spot monitoring and traffic sign recognition plus front and rear parking sensors.

Also worth calling out ‘FDE’ (Ferrari Dynamic Enhancer) which works in parallel with the SSC to help modulate lateral movement in extreme circumstances.

If a crash is unavoidable there are four airbags - dual front and dual side front (head). That’s an acceptable count in a 2+2 coupe, but it would be nice to see a front centre bag.

The MG IM5 Performance is covered by a seven-year/unlimited km warranty, which is a plus, but the catch is it’s conditional on authorised dealer servicing. Go elsewhere and the term drops to a more common five years/unlimited km. The drive battery is covered for eight years/160,000km, which is the norm in the Aussie market

Servicing is required every 12 months or 20,000km with charges averaging $586 per workshop visit for the first five years, which is on the high side for an EV, even at this price point, the average bumped up by a more than $1400 doozy at year four.

MG IM models are sold (with service available) through all of MG’s 100-plus dealerships across the country, so no concerns there.

As the name implies, Ferrari’s ‘7-Year Genuine Maintenance’ program means you won’t have to worry about servicing costs for the first seven years of ownership. Everything from labour and parts to lubricants and brake fluid is included in the free-of-charge package.

For reference, maintenance is recommended every 12 months/20,000km, which is a healthy distance and roadside assistance is complimentary for the first 12 months. 

Warranty cover is three years/unlimited kilometres, which trails the mainstream market but matches high-end competitors like Aston Martin, Lamborghini, McLaren and Porsche.
